Non-invasive methods to comply with emission regulations

Maintaining emissions below permissible levels is a critical aspect of turbine operation. Methods to achieve regulatory compliance have to be non-invasive to ensure continued operation of the turbine.

Five methods are recommended, which can be implemented by turbine owner/operators to lower emissions and increase combustion efficiency. One of the recommended practices is a new technology called Dry Low Emissions/Dry Low NOx (DLE/DLN) mapping, which analyzes signals of turbine conditions over time (please see March/April 2011 issue of Turbomachinery International magazine for more).

DLE/DLN mapping can analyze performance data from the existing control systems and field devices to determine a turbine’s actual performance. Then, adjustments can be made to the system to optimize combustion and lower emissions.
